Bug #6416: Deadlock when calling Thread#join from signal interrupt context
https://bugs.ruby-lang.org/issues/6416#change-33920

Author: ender672 (Timothy Elliott)
Status: Assigned
Priority: Normal
Assignee: kosaki (Motohiro KOSAKI)
Category: 
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2012-05-09 trunk 35598) [x86_64-linux]


=begin
The interpreter can deadlock when calling Thread#join both from the main context and from the signal handler context.

  t = Thread.new{ sleep 3 }

  Signal.trap "SIGINT" do
    t.join
  end

  puts 'Press ctrl + c now'
  t.join

The above will deadlock on linux x86_64 with ruby 1.9.x and ruby trunk. It works fine with ruby 1.8.7-p352 and JRuby.

=end
